This paper briefly reviews the fabrication and electrorheological (ER) characteristics of mesoporous materials and their nanocomposites with conducting polymers under an applied electric field when dispersed in an insulating liquid. Smart fluids of electrically-polarizable particles exhibit a reversible and tunable phase transition from a liquid-like to solid-like state in response to an external electric field of various strengths, and have potential applications in a variety of active control systems. The ER properties of these mesoporous suspensions are explained further according to their dielectric spectra in terms of the flow curve, dynamic moduli, and yield stress.
本文简要回顾了介孔材料及其与导电聚合物的纳米复合材料在分散于绝缘液体中并施加电场时的制备方法和电流变（ER）特性。电可极化颗粒的智能流体在不同强度的外部电场作用下呈现出从液态到固态的可逆且可调相变，并在各种主动控制系统中具有潜在应用。根据这些介孔悬浮液的介电谱，从流动曲线、动态模量和屈服应力方面进一步解释了它们的电流变特性。
